I am gettting the code in the subject. What does that mean?? I just have replaced that O2 sensor like 500 miles ago. It is not making the car miss but it has messed my idle up a little. I do have LT's so I cut the wire's and made them longer but I did a great job and heat shrinked all connections. I wonder if it is bad or could there be a reason for this. The last time I replaced it, it threw a low voltage code. Any help on this is appreciated.
